New port: mail/fastforward
fastforward handles qmail forwarding according to a cdb database.
It can create forwarding databases from a sendmail-style /etc/aliases
or from user-oriented virtual-domain tables.
fastforward supports external mailing lists, stored in a binary format
for fast access.It has a tool to convert sendmail-style include files
into binary lists.
fastforward is more reliable than sendmail.
sendmail can't deal with long aliases, or deeply nested aliases,
or deeply nested include files; fastforward has no limits other than memory.
sendmail can produce corrupted alias files if the system crashes;
fastforward is crashproof.
fastforward's database-building tools are much faster than sendmail's
newaliases. Even better, fastforward deliveries don't pause while the database
is being rebuilt.
fastforward does not support insecure sendmail-style program deliveries
from include files; you can use qmail's secure built-in mechanisms instead.
fastforward does support program deliveries from /etc/aliases.
